## Description

GQ GMC-300S Digital Nuclear Radiation Detector Monitor Meter Geiger Counter Radiation Dosimeter: desertcart.com: Industrial & Scientific

Review: I got what I paid for and don't regret it. - Exactly as described and well worth the price. I've tested this against some known elements in my collection and the counter works well. The interface is intuitive and easy to navigate to change various settings and customize the display. I chose this as an economical option that would still allow me to have audible and visual queues. The ability to view the data (including as a graph) and export it is appreciated, as is having a quick tool for the standard conversions and equivalent metrics of Sieverts, Rads, CPM and dose etc. Would also note the battery came charged and has held up well for hours now. I look forward to taking this on my upcoming trips to the odd mineral shop or planned conventions. Don't look at other cheaper options on desertcart from xyz brands and vendors... This product has the quality you are really looking for.
Review: It does the job and fun to have - I collect various rocks as a hobby. I once took this to the abandoned uranium mine and it promptly alerted me with a radiation level much higher than what is considered to be safe and typical background level. I also did a nuclear bone scan at a hospital and I just took this with me just to see what happens. This device alerted me with a rapid burst of static sound to warn me of the presence of radiation, especially on my arm after the technetium-99m isotope was injected into a vein. Bone scan is a relatively low radiation procedure and the half life of this isotope is very short (6 hours).

### ⭐⭐⭐⭐⭐ Seems to be an excellent radiation detector.
*by M***S on June 26, 2024*

I've worked in a facility that handles waste products that all have some level of radioactive contamination, so I am well familiar with Geiger counters. It appears to work well with a degree of accuracy. The manual is easy to understand and the functionality of the instrument and basic setup was straightforward. I like the fact that it has a built-in rechargeable battery, and a full charge will give several hours of operation. Hopefully, I will never absolutely need to use it, but in these times it was quite inexpensive and offers much mental comfort.
